Earlier this month, Loblaw committed to have a fully electric fleet as part of the company's commitment to reduce its carbon footprint by 2030.

That would involve adding 350 zero-emission vehicles and more than 2,500 trailers to the fleet.

The Ontario-based grocer said removing diesel from its transport trucks and refrigerated trailers could reduce more than 94,000 tonnes of carbon dioxide emissions annually, the equivalent of removing more than 20,000 cars from the road.

By 2030, Loblaw expects to have reduced emissions from electricity use by 35 per cent, transportation by 25 per cent, and refrigerants by 50 per cent.

First deliveries of the Tesla trucks are expected in 2019.

No price for the trucks was provided, but reservations for the Tesla Semi cost US$5,000 per truck.

Wal-Mart says it has also pre-ordered 15 vehicles, including 10 for its Canadian routes.

"We have a long history of testing new technology — including alternative-fuel trucks — and we are excited to be among the first to pilot this new heavy-duty electric vehicle," Wal-Mart spokesman Ryan Curell wrote in an email.

"We believe we can learn how this technology performs within our supply chain, as well as how it could help us meet some of our long-term sustainability goals, such as lowering emissions.”

Tesla declined to identify any other Canadian buyers for the truck that it says can go from zero to 100 kph in five seconds without a trailer, compared to 15 seconds for a comparable diesel truck.

It says the Tesla Semi requires no shifting for smooth acceleration and its brakes recover 98 per cent of kinetic energy to the battery.

"Overall, the Semi is more responsive, covers more miles than a diesel truck in the same amount of time, and more safely integrates with passenger car traffic," it said on the company's website.

Tesla says that a fully loaded Semi consumes less than two kilowatt-hours of energy per mile and has a range of about 800 kilometres. That could save owners at least US$200,000 in fuel costs over 1.6 million km.
